Phone Number for Unemployment in Massachusetts: How to Reach the DUA

If you're trying to reach the Massachusetts unemployment office by phone, you're looking for the Department of Unemployment Assistance (DUA) — the state agency that administers unemployment insurance (UI) benefits in Massachusetts.

The Main DUA Phone Number

The primary contact number for Massachusetts unemployment claimants is:

📞 877-626-6800 (toll-free within Massachusetts)

For callers outside Massachusetts: 617-626-6800

This is the DUA's main claimant services line. It handles questions about existing claims, filing issues, payment status, identity verification, and general program questions.

TTY/TDD users (for the hearing impaired) can reach the DUA at: 617-626-6overhead — check the DUA's official website for the current accessibility line, as relay service numbers are updated periodically.

DUA Phone Hours

The DUA claimant services line operates on a set schedule. As of the most recent published information:

• Monday – Friday: 8:30 AM – 4:30 PM ET
• Saturday: 8:00 AM – 12:00 PM ET (limited services)
• Sunday and major holidays: Closed

Hours are subject to change, particularly during periods of high unemployment when call volume increases significantly. The DUA has adjusted hours and staffing before — confirm current hours at mass.gov/dua before calling.

What the Phone Line Handles

Not every issue requires a phone call. The DUA's online portal — DUA QUEST Self-Service — handles many routine tasks. But the phone line is typically the right channel for:

For weekly certifications, the DUA has a separate automated phone option: 617-626-6338. This line allows claimants to certify by phone without waiting for a live representative.

Why Calls Are Sometimes Difficult to Complete

Massachusetts — like most states — fields an enormous volume of calls during economic downturns or following major layoffs. During peak periods, wait times can stretch to several hours, and some callers report being disconnected before reaching an agent.

A few patterns worth knowing:

• Early in the week (Monday and Tuesday) tends to be the busiest, as claimants often call after receiving determination letters or after weekend issues arise.
• Mid-week mornings (Wednesday–Thursday, right at open) are typically lower volume.
• Calling exactly at 8:30 AM often results in immediate queue placement before lines fill.

None of this is guaranteed — call volume is unpredictable — but timing your call can improve your odds of getting through.

When You Need More Than a Phone Call

Some DUA issues aren't resolved over the phone and require other channels:

For appeals: If you've received a disqualification or denial and want to appeal, the DUA's UI Online portal and written correspondence are both used in the appeals process. Appeals must generally be filed within 10 days of the determination date in Massachusetts — that deadline is stated on your determination letter and matters significantly.

For employer disputes: If your former employer has contested your claim, an adjudicator may need to gather information from both sides. That process typically happens through written notice and scheduled fact-finding, not a standard phone call.

For identity verification: Massachusetts uses identity verification services that sometimes flag claims and put payments on hold. If your account is flagged, the DUA may direct you to a specific verification process — resolving this by phone sometimes requires connecting with a specialized team rather than the general claimant line.

Other DUA Contact Points

For employers with questions about UI taxes, experience ratings, or claim protests, the DUA has a separate employer line — listed on the DUA employer services page at mass.gov.

What to Have Ready Before You Call 🗂️

When you reach the DUA by phone, having the following ready speeds up the call:

• Your Social Security number
• Your claimant ID or claim number (on any DUA correspondence)
• The dates in question (last day worked, week ending dates for missed certifications, etc.)
• Any determination letter or notice you're calling about — representatives will reference the specific letter code and date

One Number, Many Situations

The 877-626-6800 line connects to Massachusetts's main claimant services operation — but what happens once you're connected depends heavily on your specific claim status, whether your claim is active or pending, whether there's a hold or issue flagged on your account, and what stage of the process you're in.

The phone number gets you to the agency. What the agency can resolve — and how quickly — turns on the facts of your individual claim.
